Okay I see that fields are defined as attributes of the table class (gluon.dal.Table). The table class has a __getitem__ method defined which allows indexing by attribute name (as python allows).

Therefore I can get a list of field objects by using a list comprehension:

[db.customer[fieldname] for fieldname in db.customer.fields]
